Textile Dyeing Wastewater Treatment

, 2011
Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and ...

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Upgradation of Waste Dyed Fiber Through Production of Upcycled Rotor‐Spun Yarn: Enhancing Sustainability in Textiles

CleanMat, EarlyView.
This research is about development of upcycled yarn from textile waste. The results demonstrate that RDFW can be successfully incorporated into yarn production, maintaining comparable tensile strength and uniformity, while reducing waste and resource consumption also save up to 22,000 L of water and 1.2 kg of CO2 per kilogram of cotton.

Electrochemical treatment of textile wastewater

Water Science and Technology, 1996
The treatment of textile wastewater, containing a high concentration of Cl- ion, by an electrochemical method using Ti/RuO2, Ti/Pt and Ti/Pt/Ir electrodes is investigated. All three anodes proved to be very effective in direct or indirect oxidation of organics present in the wastewater. After 60 min of electrolysis at 6 A/dm2, COD was reduced by 85-92%
